CENTURY BANCORP, INC. ANNOUNCES 6TH CONSECUTIVE YEAR OF RECORD EARNINGS FOR 2015, UP 5.3%; LOAN GROWTH OF 30%; ASSET GROWTH TO $3.9 BB; REGULAR DIVIDEND DECLARED

Medford, MA, January 19, 2016—-Century Bancorp, Inc. (NASDAQ:CNBKA) (www.centurybank.com) (“the Company”) today announced record net income of $23,021,000 for the year ended December 31, 2015, or $4.13 per Class A share diluted, an increase of 5.3% compared to net income of $21,860,000, or $3.93 per Class A share diluted, for 2014. Total assets increased 8.9% from $3.6 billion at December 31, 2014 to $3.9 billion at December 31, 2015. For the quarter ended December 31, 2015, net income totaled $5,971,000 or $1.07 per Class A share diluted, an increase of 6.2% compared to net income of $5,623,000, or $1.01 per Class A share diluted, for the same period a year ago.

Net interest income totaled $70.0 million for the year ended December 31, 2015 compared to $66.2 million for the same period in 2014. The 5.6% increase in net interest income for the period is primarily due to an increase in average earning assets. The net interest margin decreased from 2.22% on a fully taxable equivalent basis in 2014 to 2.18% on the same basis for 2015. This was primarily the result of a decrease in rates on earning assets. The average balances of earning assets increased by 8.3% combined with a similar increase in average deposits. Also, interest expense increased 5.2% as a result of an increase in deposit balances.

The provision for loan losses decreased by $1,850,000 from $2,050,000 for the year ended December 31, 2014 to $200,000 for 2015, primarily as a result of changes in portfolio composition, related methodology enhancements to address these changes, as well as net recoveries being realized during the year. The Company’s effective tax rate decreased from 3.8% in 2014 to 2.3% in 2015 primarily as a result of an increase in tax-exempt income.

At December 31, 2015, total equity was $214.5 million compared to $192.5 million at December 31, 2014. The Company’s equity increased primarily as a result of earnings and a decrease in other comprehensive loss, net of taxes, offset somewhat by dividends paid. Other comprehensive loss, net of taxes, decreased primarily as a result of a decrease in unrealized losses on securities transferred from available-for-sale to held-to-maturity.

The Company’s leverage ratio stood at 6.79% at December 31, 2015, compared to 6.91% at December 31, 2014. The decrease in the leverage ratio was due to an increase in quarterly average assets, offset somewhat by an increase in stockholders’ equity. Book value as of December 31, 2015 was $38.53 per share compared to $34.57 at December 31, 2014.

The Company’s allowance for loan losses was $23.1 million or 1.33% of loans outstanding at December 31, 2015, compared to $22.3 million or 1.68% of loans outstanding at December 31, 2014. The change in the ratio of the allowance for loan losses to loans outstanding was primarily due to changes in portfolio composition and related methodology enhancements to address these changes. Non-performing assets totaled $2.3 million at December 31, 2015, compared to $4.1 million at December 31, 2014.

The Company’s Board of Directors voted a regular quarterly dividend of 12.00 cents ($0.12) per share on the Company’s Class A common stock, and 6.00 cents ($0.06) per share on the Company’s Class B common stock. The dividends were declared payable February 16, 2016 to stockholders of record on February 1, 2016.

The Company, through its subsidiary bank, Century Bank and Trust Company, a state chartered full service commercial bank, operating twenty-seven full-service branches in the Greater Boston area, offers a full range of Business, Personal and Institutional Services.

Century Bank and Trust Company is a member of the FDIC and is an Equal Housing Lender.
